Resistive ribbon printing is a method of printing that employs the 1/2/R principle. That is, electric current is passed through a layer of a known resistance at discrete points, causing a heat-sensitive ink to melt and form the desired pattern. By replacing the carbon normally employed in the ink with a magnetic media pigment, such as chromium dioxide (CrO(2)), a magnetically sensitive print can be made. In this way there is obtained high quality print which has magnetic recognition properties.
